Hi John,
Greetings from syncfusion.
Currently, DataGrid does not have the support for export the DataGrid to pdf. We have already logged the feature request. This feature will be implemented in any of our upcoming release.
You can refer the below feedback link for further follow up,
Moreover, you can achieve your requirement by converting the DataGrid to an image.
